CPS测试（每秒点击次数）.

What is a good CPS score?

Most people land between 4 and 7 clicks per second with normal clicking. Above 7 CPS is fast, and sustained scores of 10+ CPS usually involve techniques like jitter clicking, butterfly clicking or drag clicking rather than ordinary clicking. Short windows (1s) always score higher than long ones (60s) because you cannot sustain a burst rate.

When does the timer start?

The timer starts on your first click, not when the page loads. That means your reaction time and any hesitation before you begin are not counted against your score - the full window is spent clicking.

Which test length should I pick?

Use 5 or 10 seconds to compare against most online leaderboards, since those are the standard windows. Use 1 second to measure peak burst speed, and 30 or 60 seconds to measure endurance, which is what actually matters in games.

How accurate is the measurement?

Timing uses performance.now(), a monotonic high-resolution clock, rather than Date.now(). That matters for short tests: Date.now() has coarse resolution and can jump if the system clock is adjusted or synced mid-test, which would corrupt a 1-second measurement.

Is my personal best saved?

Yes, your best CPS is stored in your browser's local storage on your own device. It is never uploaded, and clearing your browser data or using private browsing will reset it.
